A resistance system for a rowing machine has a mounting bracket, and a housing assembly, a driving assembly and a restoring assembly mounted on the mounting bracket. The housing assembly is for storing liquid and a paddle wheel. The driving assembly is connected to the paddle wheel and drives the paddle wheel to rotate in a direction only. The restoring assembly is connected to a strip hub of the driving assembly and is able to drive the strip hub to rotate in a reverse direction. The resistance system for the rowing machine has simplified structure. Therefore, it is easy to assemble to resistance system, and manufacturing cost of the resistance system can be decreased. In addition, a service life of the resistance system as well as the rowing machine can be increased.

The present invention relates to systems and devices for improving of a rower's technique. In particular, the invention provides one or more clamps that can be used in conjunction with a rowing machine to provide external cues that the rower can use to monitor and correct his or her catch technique without the assistance of a coach or other person.

User activity including both athletic activity (e.g., running, walking, etc.) and non-athletic activity (shopping, reading articles, etc.) may be monitored and tracked by an athletic monitoring and tracking device and service. The user activity may be used to award a user with an amount of virtual currency to encourage the user to continue various activities. In one example, users may use the virtual currency to purchase or otherwise acquire various products, services, discounts and the like. A user may track an amount currency earned and/or needed relative to an amount required to acquire a desired product or service. Additionally or alternatively, a visual appearance of a user device (e.g., a watch or athletic activity band) may change based on the user's activity level, an amount of virtual currency earned and the like.

A translatable carriage exercise machine comprising first and second spaced elongate side rails. A moveable carriage translatable along the side rails. An upper support surface on the carriage sized to support the entire posterior trunk of an adult human in supine. A plurality of elastic tension members secured to a bottom of the moveable carriage and fixable to a plurality of spring anchors. An upright footbar positioned at a machine first end. A pair of carriage pulleys fixed at a second end of the exercise apparatus with carriage ropes adjustably fixed to the moveable carriage each looped around respective carriage pulleys. A rotational resistance mechanism comprising an elongate resistance band having an extended configuration and a retracted configuration. The rotational resistance mechanism comprising a resistor comprising a load member. A user option to utilize one or more of the elastic tension members and rotational resistance mechanism during exercise.

An exercise machine includes a cyclical actuator and a mechanical energy storage device. Connective structure operatively connects the cyclical actuator to the mechanical energy storage device. Motion of the cyclical actuator urges physical motion of and energy storage in the mechanical energy storage device. The exercise machine further includes an electric machine. A communication pathway enables exchange of data between multiple associated exercise machines such that multiple associated operators on multiple associated exercise machines have a common experience.

Embodiments for a multi-functional exercise system with variable resistance are provided. The system includes a base plate such as an exercise plate weight, cover plates, omnidirectional wheels, a protective skirt frame, and various attachment adapters. These are structured such that the top cover plate is attached to a top face of the base plate and a bottom cover plate is attached to a bottom face of the base plate, the omnidirectional wheels and protective skirt frame are attached to the bottom cover plate, and the attachment adapters are fastened to a central aperture defined by the base plate. The described embodiments allow a user to use this exemplary system to perform multiple exercises with various attachments.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

A board paddling training apparatus for assisting in improving a user's paddling technique and strength. In particular, the board paddling training apparatus includes a buoyant board, such as a board adapted for surfing, bodyboarding, paddleboarding, or other board-related sport that entails paddling, and includes a resistance mechanism that creates drag or resistance against a user's paddle stroke. Some implementations of the resistance mechanism can be adjustable in order to create a variety of resistance against the user's paddle stroke and board movement.
